2010 Rieju Marathon 250 Technical Analysis & Specification Breakdown

At the heart of the 2010 Rieju Marathon 250 enduro - offroad motorcycle, Rieju utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches).

On the scales, the Marathon 250 measures 98 kg (216 lbs) dry. Rider ergonomics and chassis geometry center around a 945 mm (37.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,476 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
